Introduction: The title is a bit interesting, but a little problematic. The first is that Goguryeo is not Goryeo which are two different regimes. Secondly, Goguryeo was not a land of bullets, and at its peak its heyday, it was a regional power in the east of the two provinces of Jilin and Liaoning in China, and south of the Datong River basin of the East Han Peninsula. The estimated area also exceeds the 200,000 square kilometers of territory of the Korean Peninsula. Goguryeo lasted more than 600 years from the beginning of the Han Dynasty to the fall of the Tang Dynasty, and reached its peak during the Southern and Northern Dynasties before the establishment of the Sui Dynasty. Whether it is from the overall system, the county system, or the law, Goguryeo is a regime highly similar to the Civilization of the Central Plains, and the population of warlike soldiers has reached 600,000. The history of Goguryeo is roughly divided into three stages: the first stage: the stage of silent development before the almost annihilation of the state by Cao Wei. The second stage was from the Sixteen Kingdoms of Wuhu to the Southern and Northern Dynasties in order to continuously encroach on the territory of the Central Plains Liaodong, and the territory reached its peak stage. The third stage: in the Sui and Tang dynasties, the repeated conquests of the four emperors of the two dynasties finally destroyed this major problem. As for why Goguryeo made sui and Tang so headlines, the reasons for this are manifold, and we will elaborate below.
First of all, goguryeo is the regime established by the Buyeo people in our country, and later extended to the Korean Peninsula. The ethnic group was dominated by the Yu and buyeo people, and later absorbed some of the Jing people and the Three Koreans. Goguryeo lasted for more than 600 years from the time of the Han Dynasty in 37 AD to its destruction by the Tang Dynasty in 668 AD.
Goguryeo originally did not border the Central Plains, and began to encroach on the territory of western Liaoning during the Three Kingdoms period due to the annihilation of the Gongsun clan of Liaodong by Cao Wei. This annoyed Cao Wei and sent Yuqiu Jian to lead troops to attack the Goguryeo capital city of Maru, and Goguryeo almost perished. During the history of the great turmoil in the Central Plains during the Two Jin Dynasties and the Northern and Southern Dynasties, no one can estimate that Goguryeo in the northeast can only let it develop. Therefore, during this period, Goguryeo encroached on the territory of the Central Plains Liaodong and reached its peak. When the Sui Dynasty ended hundreds of years of splitting and unifying the country, no one could tolerate an independent regime around them. Therefore, the four emperors of the Sui and Tang dynasties continued to attack, and finally pacified Goguryeo during the reign of Emperor Gaozong of Tang. Why the four emperors of the Sui and Tang dynasties regarded Goguryeo as a constant attack on their confidants was mainly due to the following reasons:
Goguryeo was not a nomadic regime, but had a distinctly centralized nature that had been passed down through the centuries as a powerhouse in Northeast Asia
Goguryeo was established by the ancient Buyeo people, with a centralized transition of complete inheritance. This dynasty, which usually only exists in the Central Plains, first appeared in the Northeast. At that time, although the Sui and Tang Dynasties were strong enough to exert influence and radiation on Northeast Asia, no one really controlled it. In line with the Confucian tradition of the universal kingdom, such a regime could either be incorporated into the Central Plains Dynasty or destroyed before it could be civilized, so that it could not exist outside the Central Plains Dynasty.
Goguryeo was governed by a strict hierarchy and a system of county governance, and its laws, culture, and even religious beliefs were in line with the Central Plains. Therefore, such a transition cannot be incorporated into the Central Plains Dynasty, and it can hardly be regarded as a completion of unification. If according to Tang Taizong Li Shimin's saying, it is: "Now the Nine YingDa Ding, only this corner."
During the Sui and Tang dynasties, Goguryeo was untamed, strong and powerful
Goguryeo's territory of more than 200,000 square kilometers was home to millions of people, and the number of troops exceeded 600,000 at its peak. Domestic warriors are extremely aggressive, and they are heavily armed. Stable soldiers, a steady stream of food production, and warriors who could fight in battle all gave Goguryeo ambitions, so even the Sui and Tang dynasties were not convinced. For the Sui and Tang dynasties, which were also strong in China's history, it was called the Heavenly Dynasty, how could it be possible to allow a small hegemon in Northeast Asia to point fingers at the doorstep of his home all day.
Goguryeo not only directed the Central Plains Dynasty, but also continued to invade and occupy the territory of western Liaoning. This annoyed the Sui Emperor Yang Jian, but the Central Plains Dynasty had always paid attention to the famous teachers, so it wrote a threatening letter to the Goguryeo monarch: "The vastness of the Liaoshui River, how can it be like the Yangtze River? Goryeo people, how many Chen Kingdoms? If there is no existence of yu, blame the king for his former sorrows, and order a general, why wait for more power!". Goguryeo hastily withdrew its troops to atone for its crimes, but Goguryeo's typical jiguryeo continued to encroach on the territory of the Sui Dynasty, which caused the Sui Dynasty to panic and war broke out.
In fact, Goguryeo has long been used in a pure way, but before that it was a historical era of division. At that time, the change of regime was relatively fast and could not take care of it, so it gradually grew to encroach on the territory. But this time he encountered Sui and Tang, and although he was brave for a while, he was doomed to be swept away.
Goguryeo once had a strategy of joining forces with the Turks against the Sui and Tang Dynasties, which made the Sui and Tang feel that it was more aggressive. Therefore, when the national strength is strong, we must destroy him, prevent Goguryeo from making a big harm to the Central Plains, and let Liaodong become a barbarian land
By the time of the Sui and Tang dynasties, Goguryeo was already a centralized country that had been passed down for more than 600 years, and its soldiers were strong and strong. This kingdom broke through the shackles of the feudal dynasty in the Central Plains that could not exceed three hundred years, which made the visionary emperors of the Sui and Tang dynasties extremely wary of it. If we could not take advantage of the great unification of the Sui and Tang dynasties to eliminate it, in case the Central Plains fell into a split, we could only sit back and watch Goguryeo grow bigger. If Goguryeo expanded indefinitely, it would be a disaster for the Central Plains Dynasty. Therefore, the sui emperor Yang Jian, the Sui emperor Yang Guang, the Tang Taizong Li Shimin, and the Tang Gaozong Li Zhi emperor continued to attack Goguryeo and finally succeeded.
Although Goguryeo was in the same vein as all aspects of the Central Plains, its encroachment on the territory of the Central Plains and its hostility to the Central Plains Dynasty made the Confucian ministers regard it as barbarians. Because from the Zhou Dynasty period, this place was the hometown of Jizi Joseon, Guzhu Kingdom and Han Four Counties, so it belonged to the Han family. At this time, it was actually invaded and occupied by barbarians, and it was certainly impossible to run this Han family homeland and become the land of barbarians. Moreover, Goguryeo was suppressed by the Sui and Tang Dynasties, and actually went with the Turks to plan to attack the Sui and Tang Dynasties. This was truly intolerable, and the continuous attack spanning 70 years finally calmed Goguryeo. This degree of difficulty is similar to the three generations of emperors of the Qing Dynasty quelling the rebellion of the northwestern Dzungars.
brief summary:
In summary, Goguryeo is a northeastern bully with a centralized system of cultural heritage. This kingdom spanned more than 600 years and was extremely aggressive and disobeyed to the administration of the Central Plains Dynasty, so the Sui and Tang emperors with a sense of crisis spared no effort to complete the pacification of Goguryeo.
I am the emperor of history, welcome your attention; if there is a flaw, the axe is right.
